(01. 118-59) This invention relatesto twisting machines of An oil receptacle 30 surrounds the upperporthering type, particularly designed for twisting tion or the ring holder 12andispreferablyperrelatively heavy thread or yarn. In such mamanentlyassembled therewith by forcing the re- I chines, the excessive pull onthe traveler renders .ceptacle 30 over the upper end of the holder 12 or5 lubrication of the rings desirable to reduce travby welding orotherwise securing these parts in 5 eler wear and replacement.

All parts are simple and easily constructed, and the advantages of ourinvention may be utilized at very slight increase in cost over theordinary construction in which manual lubrioation is commonly necessary.

Having thus described our invention and the advantages thereof, we donot wish to be limited to the details herein disclosed, otherwise thanas set forth in the claims, but what we claim is:

1. In a ring twisting machine having a ring rail with a circular ringaperture, in combination, a vertical-flange twister ring, a ring holdertherefor snugly fitting the aperture in said ring rail and having anannular oil-collecting channel in its lower portion, and means to supplyoil to said ring, said ring, ring holder and oil supply means forming aseparately assembled unitary means to supply oil to said ring, saidring, .ring' holder and oil supply means forming a separately assembledunitary structure.

3. In a ring twisting machine having a ring rail with a circular ringaperture, in combination, a vertical-flange twister ring, a ring holdertherefor snugly fitting the aperture in said ring rail and having anannular oil-collecting channel in its lower portion, a substantiallyannular oil receptacle mounted on the upper part of said holder andproviding an external shoulder to engage the ring rail and verticallyposition said ring holder, and a wick extending from said receptaclethrough radial openings in the ring to the inner face thereof, saidring, ring holder and oil receptacle forming a separately assembledunitary structure. r

' 4. In a ring twisting machine having an apertured ring rail, incombination, a vertical-flange twister ring, a ring holder thereforhaving an annular oil-collecting channel in its lower portion, asubstantially annular oil receptacle mounted on the upper part of saidholder and providing an external shoulder to engage the ring rail andvertically position the ring holder, a wick extending from saidreceptacle through radial openings in the ring to the inner facethereof, and a cover for said receptacle fitting between said ring andthe outer wall of said receptacle and effectively excluding dirt fromsaid receptacle, said cover having an oil opening at one part thereofand having an upwardly displaced portion shielding the wick at anotherpart..
